CyberRota Analysis

AI-Generated

The vulnerability affects Coder's remote development environment provisioning via Terraform, where improper handling of the `email_verified` claim can lead to account takeover if the claim is returned as a non-boolean or omitted. This flaw allows attackers to exploit the system's fallback mechanism for email-based account linking, potentially compromising user accounts. Organizations using affected versions should prioritize upgrading to versions 2.29.7, 2.32.7, 2.33.8, or 2.34.2 to mitigate this high-severity risk.

Original NVD Description

Coder allows organizations to provision remote development environments via Terraform. Prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2, Coder's OIDC callback checked `email_verified` with a direct Go `bool` type assertion. When an IdP returned the claim as a non-boolean (for example the string `"false"`) or omitted it, the assertion failed open and the email was treated as verified. Combined with an unconditional email-based account fallback, this enabled account takeover. The fix in versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2 coerces `email_verified` across bool, string and numeric types (fail-closed) and blocks the email fallback when the matched user already has a different linked IdP subject. As a workaround, ensure the IdP returns `email_verified` as a native JSON boolean. The email-fallback linking issue has no configuration workaround; upgrading is required.
